Siemens to deliver Romania’s First Hydrogen-Powered Train Fleet
“We
are proud to deliver the first fleet of hydrogen trains for Romania. With the
Mireo Plus H, we combine a proven regional train platform with state‑of‑the‑art hydrogen technology, enabling zero‑emission rail operations on non‑electrified lines. Hydrogen will play a key role in
achieving climate‑neutral mobility in Europe,
and this project clearly demonstrates how innovation can be translated into
reliable and economically attractive rail solutions,” said
Andre Rodenbeck, CEO Rolling Stock at Siemens Mobility.
Hydrogen propulsion and
energy efficiency
The
Mireo Plus H features a hydrogen fuel cell-based electric propulsion system,
complemented by battery energy storage. The batteries are charged either via
the fuel cell system or through regenerative braking, enabling highly efficient
energy use and zero local emissions during operation.
Siemens
Mobility has optimized the vehicle concept to significantly reduce weight,
component complexity, energy consumption, and maintenance costs. All key
onboard components have already been validated in previous Siemens Mobility
projects, ensuring a high level of technical maturity and operational
reliability.
Mireo Plus H – a modern regional train for Romania
The trains for Romania are based on the Siemens Mireo platform and configured as articulated two-unit trainsets with a maximum operating speed of 120 km/h. Each trainset offers 131 fixed seats plus 5 folding seats, providing a high level of passenger comfort while ensuring operational efficiency. The trains can be operated in multiple traction of up to two coupled units, offering flexibility for both current and future operational requirements.
Safety systems and passenger
information
The
vehicles will be equipped with PZB (intermittent train control) train
protection systems and European Train Control System, ensuring compliance with
European safety and interoperability standards. A modern Passenger Information
System will provide continuous travel information through interior and exterior
displays as well as automated announcements, enhancing the travel experience for
passengers and supporting operational staff.
Comprehensive service scope
and local presence
In
addition to vehicle delivery, the contract includes a comprehensive
full-service maintenance package with a duration of 15 years, extendable by
another 15 years. Maintenance activities will be carried out locally in
Romania, including at a dedicated depot in Bucharest, by Siemens Mobility
personnel, supported by Railigent X digital maintenance and fleet management
systems designed to optimize availability and extend component and battery
lifetimes.
The
scope delivers a fully integrated, end-to-end service solution, combining
preventive and corrective maintenance, comprehensive overhauls, full Entity in Charge
of Maintenance responsibility, and seamless material supply, ensuring optimal
train availability and consistently smooth, reliable operations.
By
replacing diesel-powered rolling stock, the new hydrogen trains will contribute
to a significant reduction of emissions and noise in regional rail transport,
supporting Romania’s long-term sustainability and climate objectives. The Mireo Plus H and the Mireo Plus B are part of Siemens Mobility’s
successful Mireo platform, which comprises 24 fleets and nearly 600 trains.
They stand for modern technology, high energy efficiency with savings of up to
25 percent, and the advantages of a standardized vehicle platform that enables
synergies and economic benefits.
